PalusolTM - The World's Best Fire Seal!

2. EFFECTIVE FIRE SEAL - Some manufacturers use cheaper door seals to save money. We've tried them all. None work as well as Palusol™- the best heat-expanding fire seal on the market today (by far).

Palusol™ expands to 7 times its size when temperatures reach 212 degrees, sealing off both heat and smoke.

What makes Palusol™ so effective is that it maintains its expanded form even when the temperatures reach 1200-1400 degrees. Other seals just fall apart and let the heat in. Palusol™ maintains its seal when the heat is on!
